Some 500 foraminiferal species have been identified from Lower Cretaceous deposits of the Crimea, benthos being predominant among them. There were nearly 300 species altogether of planktonic forms.
Most species are widely distributed; they have been known from corresponding deposits of West Europe, North Africa, the North Caucasus and Turkmenia. Endemic species can be found too. Subdivision based on foraminifera is possible up to a suhsfage and
sometimes to a stage in the interval from Berriasian to Barremian. A more detailed
subdivision of Aptian and Albian deposits has been carried out according to planktonic
foraminifera. Some stages can be distinguished in the development history of Early
Cretaceous foraminifera of the Crimea. The first stage corresponding to the Berriasian —
Goeterivian time is closely related to the Late Jurassic stage of the fauna development.
The secoqd stage falling on the Barremian age is the period of reconstruction and well
pronounced renovation of the fauna composition at the expense of appearance and development of new representatives of rotailiids. And, at last, the third stage corresponding
to the Aptian—Albian time concerning the character of fauna, gravitates considerably
to the Upper Cretaceous epoch. A characteristic of fauna concerning stages is presented,
as well as a table of stratigraphic distribution of the most peculiar foraminifers and
their pictures and description of 10 new species and 1 new genus.
